I am trying to access Secure server running on tomcat, using java client. I am getting a

javax.net.ssl.SSLPeerUnverifiedException

.
I imported the certificate to a keystore and I am using the following statement to make it a trusted certificate.

System.setProperty("javax.net.ssl.truststore", path_to_my_keystore);

It is still giving me the above mentioned exception.
Any help would be greatly appreciated.
Thanks.
